Old Taito 3 board set
=====================
These pinouts are not 100% complete, but there is enough info for an
upright JAMMA conversion. There is an upright/cocktail pin
somewhere and 2P left/right/fire buttons are still unidentified.
The HALT pin was the one that had me going for a while. I couldn't
get the game to run at all outside the cocktail harness until I wired
this sucker low.
Lunar Rescue ('80)
Space Invaders (late '70s)

The +15V pins don't appear to be used on either of my board sets
(Lunar Rescue or Space Invaders) and the game does work without
them wired to anything.
